【 摘 要 】

Study on present status of groupers fishes at waters of Kotania Bay was conducted from 2016 to 2017. Survey and Participatory Rural Appraisal (PRA) method were used to collect and examine data and information concerning species potential and utilization of these species. The result shows that there are 35 species of grouper fishes inhabit Kotania Bay waters. From six genera recorded, Epinephelus found to have more varieties species richness compared to other five genera. In general, main habitat of adult grouper is coral reef, whilst mangrove and seagrass are habitat for nursery and grow out. The potency of the Epinephelus, Cephalopholis and Plectropomus genus tend to decrease started in 2000 up to 2017. At the same period, the production of these genera was also declined. Species potency and production declined was attributable to habitat (coral reef) degradation and high fishing intensity as a result of high market demand. Hand line, bottom long line and trap net are general fishing gear used in harvesting of theses fishes. Fishing activities took place all year round except for bottom long line which only lasted from June to October (East monsoon). Spatial fishing ground distribution is predominantly at coral reef ecosystem of Kotania Bay.
